Every year Treehouse closes for three weeks in September, but it's not for a vacation! Instead, we do a deep, thorough cleaning of the entire Museum and take care of painting and maintenence projects that are hard to do when we're open.

One of the biggest projects during this time is to clean our giant tree. It takes several days and quite a few staff members to drape parts of the tree with plastic and then wash the dust off with "wands" that mist the thousands of leaves on our tree with water. At this time, you could say Treehouse becomes a Rain Forest.

Here's some pictures for you to enjoy of this year's tree cleaning.
